　従来の食品成形装置におけるシャッタ装置においては、生地を分割成形、あるいは包み込み成形する際に生地カスが発生することがあった。生地カスは隣接するシャッタ片間の隙間に生地が入り込みシャッタ片に付着することによって発生する。この隙間に生地が入り込む原因としては、シャッタ片造形時の歪みやシャッタ装置のシャッタ片駆動部のバックラッシュによる位相のずれ等が挙げられる。一般的に、部品同士が摺動する箇所が摩耗することは不可避であるため、前記隙間はシャッタ装置の稼働時間が累積するにつれて増大する傾向にある。摩耗によるシャッタ片同士の隙間の増大は、生地カスの増加をもたらし、作業環境に好ましくない影響を与える可能性がある。 In the shutter device in the conventional food molding apparatus, the dough residue may be generated when the dough is divided or encased. The cloth residue is generated when the cloth enters the gap between the adjacent shutter pieces and adheres to the shutter piece. Reasons for the fabric to enter the gap include distortion during molding of the shutter piece, phase shift due to backlash of the shutter piece drive unit of the shutter device, and the like. In general, it is inevitable that the part where the parts slide is worn, so the gap tends to increase as the operating time of the shutter device accumulates. An increase in the gap between the shutter pieces due to wear results in an increase in cloth waste, which may adversely affect the work environment.
　従来の食品成形装置における回転シャッタ装置においては、前記の生地カス増加の問題に対し、隣接したシャッタ片同士を摺動自在に押接することによって解決を図っていた。すなわち、シャッタ片の刃先の位置を調整可能とし、隣接したシャッタ片同士を互いに押圧して設けることによって前記の隙間を縮小させ、生地カスの発生を低減させていたのである。この方法は生地カスの発生を低減するものの、シャッタ片の摩耗を促進することとなり、再度の刃先調整や新しいシャッタ片への交換など、操作性や経済性の課題は残る。 In the rotary shutter device in the conventional food molding apparatus, the problem of the increase in the dough residue has been solved by pressing the adjacent shutter pieces slidably. That is, the position of the blade edge of the shutter piece can be adjusted, and the adjacent shutter pieces are pressed to each other to reduce the gap, thereby reducing the occurrence of cloth waste. Although this method reduces the occurrence of cloth waste, it accelerates the wear of the shutter piece, and there remain problems in operability and economy, such as adjusting the blade edge again and replacing it with a new shutter piece.
　また、隣接したシャッタ片同士が互いに押接されながら回転するため、長時間稼働、さらには、高温生地の成形の際にはシャッタ片の熱膨張が発生し、シャッタ片同士がさらに強く押接される。その結果、駆動部への負荷が過重となり駆動部が破損するおそれがある等の問題がある。加えて、このとき互いに押接されたシャッタ片もまた摺動箇所が摩耗するため、生地カス防止効果が長期的に持続するとは見込めなくなってしまう。 Further, since the adjacent shutter pieces rotate while being pressed against each other, the shutter pieces rotate for a long time, and further, the thermal expansion of the shutter pieces occurs at the time of forming the high-temperature fabric, and the shutter pieces are further pressed against each other. The As a result, there is a problem that the load on the drive unit becomes excessive and the drive unit may be damaged. In addition, since the sliding portions of the shutter pieces pressed against each other at this time also wear, it is impossible to expect that the cloth waste prevention effect will last for a long time.
　本発明は、上記に鑑みてなされたものであって、シャッタ片の先端部が隣接したシャッタ片と摺動自在に接触する接触圧が常にほぼ一定に保持されるシャッタ片及び食品成形装置を提供することを目的とする。 The present invention has been made in view of the above, and provides a shutter piece and a food molding apparatus in which the contact pressure at which the front end of the shutter piece comes into slidable contact with the adjacent shutter piece is always kept substantially constant.

　以下、図面を用いて本発明の実施形態に係る食品成形装置及び当該食品成形装置におけるシャッタ装置に使用されるシャッタ片の構成について説明する。 Hereinafter, the configuration of the food molding apparatus according to the embodiment of the present invention and the shutter piece used in the shutter device in the food molding apparatus will be described with reference to the drawings.
　本発明の第１の実施形態に係る食品成形装置１は、図１に示すごとき構成である。この食品成形装置１の全体的構成は、既に公知であるから、全体的構成については概略的に説明することとする。食品成形装置１は、本体フレーム３を備えており、この本体フレーム３上には、例えば外皮材を供給する第１のホッパー５を備えた外皮材供給装置７が備えられていると共に、例えば内包材を供給する第２のホッパー９を備えた内包材供給装置１１が備えられている。さらに、前記本体フレーム３には、重合ノズル装置１３が備えられている。上記重合ノズル装置１３は、前記内包材供給装置１１から供給された棒状の内包材の周囲に外皮材を被覆した状態に重合する作用をなすものである。 The food molding apparatus 1 according to the first embodiment of the present invention has a configuration as shown in FIG. Since the overall configuration of the food molding apparatus 1 is already known, the overall configuration will be schematically described. The food molding apparatus 1 includes a main body frame 3. On the main body frame 3, for example, an outer skin material supply device 7 including a first hopper 5 for supplying an outer skin material is provided. An inner packaging material supply device 11 including a second hopper 9 for supplying the material is provided. Further, the main body frame 3 is provided with a superposition nozzle device 13. The superposition nozzle device 13 serves to superpose the rod-like inner packaging material supplied from the inner packaging material supply device 11 so as to cover the outer skin material.
　前記重合ノズル１３の下側には、当該重合ノズル１３から下方向に流下される棒状の食品生地を切断するシャッタ装置１５が備えられている。このシャッタ装置１５は、同一円上に等間隔に配置して備えた複数の回転軸１７にシャッタ片１９を備えた構成である。上記シャッタ装置１５は、複数のシャッタ片１９によって囲繞された領域内を棒状の食品生地が下降するとき、前記シャッタ片１９を開閉動作して前記食品生地を包被切断することにより、外皮材でもって内包材を包み込んだ状態の食製品２１を製造する作用をなすものである。 A shutter device 15 for cutting a bar-shaped food dough that flows downward from the polymerization nozzle 13 is provided below the polymerization nozzle 13. The shutter device 15 has a configuration in which shutter pieces 19 are provided on a plurality of rotating shafts 17 arranged at equal intervals on the same circle. When the rod-shaped food dough descends in the area surrounded by the plurality of shutter pieces 19, the shutter device 15 opens and closes the shutter piece 19 to enclose and cut the food dough. Thus, the food product 21 in a state of being wrapped with the inner packaging material is produced.
　前記シャッタ装置１５の下側には、製造された前記食製品２１を次工程へ搬送するためのベルトコンベア等のごとき搬送装置２３が備えられている。さらに、前記食品成形装置１には、食品成形装置１の全体の動作を制御する制御装置２５が備えられている。 The lower side of the shutter device 15 is provided with a transport device 23 such as a belt conveyor for transporting the manufactured food product 21 to the next process. Further, the food molding apparatus 1 is provided with a control device 25 that controls the overall operation of the food molding apparatus 1.
　上記構成のごとき食品成形装置１によって食製品２１を製造するには、前記シャッタ装置１５における各シャッタ片１９の先端部は、隣接したシャッタ片１９に接触した状態でもって開閉動作を繰り返すものである。したがって、長時間使用すると、摩擦熱によってシャッタ片１９が熱膨張したり、シャッタ片１９の先端部に摩耗を生じ易いものである。なお、食品成形装置としては、前述したごとき構成に限ることなく、前記特許文献４に記載のごとく、食品生地供給手段によって、開閉動作する各シャッタ片の間へ偏平状の外皮材を供給すると共に内包材を供給し、前記外皮材の周縁部を中央へ寄せ集めて食製品を製造する食製品成形装置におけるシャッタ装置においても前述したごとき問題を有するものである。 In order to manufacture the food product 21 with the food molding apparatus 1 having the above-described configuration, the distal end portion of each shutter piece 19 in the shutter device 15 repeats opening and closing operations while being in contact with the adjacent shutter piece 19. . Accordingly, when the shutter piece 19 is used for a long time, the shutter piece 19 is likely to thermally expand due to frictional heat, or the tip of the shutter piece 19 is easily worn. The food molding apparatus is not limited to the above-described configuration, and as described in Patent Document 4, the food dough supply means supplies a flat outer skin material between the shutter pieces that are opened and closed. The shutter device in the food product forming apparatus that supplies the inner packaging material and collects the peripheral edge portions of the outer skin material to the center to produce the food product also has the above-described problems.
　そこで、本実施形態に係るシャッタ片１９は、図２に示すごとく構成してある。すなわち、シャッタ片１９は、前記シャッタ装置１５における回転軸１７に取付けるための取付孔２５を形成した取付ベース２７を備えている。そして、上記取付ベース２７には、同一形状の板状の半シャッタ片２９が一体的に備えられている。上記各半シャッタ片２９は、前記取付孔２５の軸心Ｏを中心として点対称に備えられている。すなわち、シャッタ片１９は、同一形状の半シャッタ片２９を点対称に備えていることによって構成してある。なお、シャッタ片１９は、半シャッタ片２９を予め一体化した形態、すなわちシャッタ片１９の全体を１枚の板材によって構成することも可能である。 Therefore, the shutter piece 19 according to the present embodiment is configured as shown in FIG. That is, the shutter piece 19 includes an attachment base 27 having an attachment hole 25 for attachment to the rotary shaft 17 in the shutter device 15. The mounting base 27 is integrally provided with a plate-shaped semi-shutter piece 29 having the same shape. Each of the half shutter pieces 29 is provided point-symmetrically about the axis O of the mounting hole 25. That is, the shutter piece 19 is configured by providing the same-shaped semi-shutter piece 29 with point symmetry. The shutter piece 19 can be configured by integrating the half-shutter piece 29 in advance, that is, the entire shutter piece 19 can be constituted by a single plate.
　前記シャッタ片１９に備えた各半シャッタ片２９は同一形状であるから、一方の半シャッタ片２９の構成について詳細に説明し、他方の半シャッタ片２９において同一機能を奏する構成要素には同一符号を付することとする。前記半シャッタ片２９は、板状部材から構成してあって、前記取付ベース２７に取付けた基端部側は幅広に形成してあり、基端部側から先端部側へ離れるに従って次第に幅が狭くなる形状に形成してある。そして、複数のシャッタ片１９によって囲繞された領域を形成し、閉動作時に食品生地の外皮材を押圧する作用をなす押圧側面３１は凸面に形成してあり、反対側の非押圧側面３３は凹面に形成してある。そして、上記押圧側面３１と非押圧面３３との交差位置が先端部３５に形成してある。 Since each half shutter piece 29 provided in the shutter piece 19 has the same shape, the configuration of one half shutter piece 29 will be described in detail, and the constituent elements having the same function in the other half shutter piece 29 have the same reference numerals. Will be attached. The half-shutter piece 29 is composed of a plate-like member, and the base end side attached to the mounting base 27 is formed wide so that the width gradually increases as the distance from the base end side to the tip end side increases. It is formed in a narrow shape. And the area | region enclosed by the several shutter piece 19 is formed, the pressing side surface 31 which makes the effect | action which presses the outer skin material of food dough at the time of closing operation is formed in the convex surface, and the non-pressing side surface 33 on the opposite side is a concave surface Is formed. An intersection position between the pressing side surface 31 and the non-pressing surface 33 is formed at the distal end portion 35.
　より詳細には、前記押圧側面３１は、図４（図４においては、シャッタ片１９は点対称形であるので、シャッタ片１９の一部を省略して図示してある）に示すように、シャッタ装置１５における各回転軸１７を矢印Ｒ方向に回転して、複数のシャッタ片１９によって囲繞された囲繞領域３７を閉動作するときに、上記囲繞領域３７が零になるまで隣接したシャッタ片１９における先端部３５が摺接する摺接面に形成してある。また、前記押圧側面３１は、半シャッタ片２９の厚さ方向に対して直交する方向、すなわちシャッタ片１９の回転方向（矢印Ｒ方向）へ突出した突出部を備えた凸曲面に形成してある。前記半シャッタ片２９における上下の平面に対する前記突出部の突出量は、前記基端部側から先端部３５に近づくに従って次第に大きく形成してある。 More specifically, as shown in FIG. 4 (in FIG. 4, the shutter piece 19 is a point-symmetrical shape, a part of the shutter piece 19 is omitted), as shown in FIG. When each rotary shaft 17 in the shutter device 15 is rotated in the direction of the arrow R to close the surrounding area 37 surrounded by the plurality of shutter pieces 19, the adjacent shutter pieces 19 until the surrounding area 37 becomes zero. Is formed on the sliding contact surface with which the front end portion 35 is in sliding contact. Further, the pressing side surface 31 is formed in a convex curved surface provided with a protruding portion that protrudes in a direction orthogonal to the thickness direction of the half shutter piece 29, that is, in the rotation direction of the shutter piece 19 (arrow R direction). . The protruding amount of the protruding portion with respect to the upper and lower planes in the half shutter piece 29 is formed to gradually increase from the proximal end side toward the distal end portion 35.
　前記非押圧側面３３は、前記囲繞領域３７が零になった後に、各シャッタ片１９が矢印Ｒ方向へさらに回転して、開動作するときに、隣接したシャッタ片１９の先端部３５の回転を許容可能に形成してある。すなわち、前記非押圧側面３３は、半シャッタ片２９の厚さ方向に対して直交する方向、すなわちシャッタ片１９の回転方向（矢印Ｒ方向）に凹んだ凹曲面に形成してある。そして、半シャッタ片２９における上下の平面に対する凹め量は、前記基端部側から先端部３５に近づくに従って次第に大きくなる形状である。 The non-pressing side surface 33 rotates the front end portion 35 of the adjacent shutter piece 19 when each shutter piece 19 further rotates in the direction of the arrow R after the surrounding area 37 becomes zero and opens. It is formed to be acceptable. That is, the non-pressing side surface 33 is formed in a concave curved surface that is recessed in the direction orthogonal to the thickness direction of the half shutter piece 29, that is, in the rotation direction of the shutter piece 19 (arrow R direction). And the amount of depressions with respect to the upper and lower planes in the half-shutter piece 29 has a shape that gradually increases from the base end side toward the tip end portion 35.
　図４（Ａ）に示すように、複数のシャッタ片１９によって囲繞された囲繞領域３７を小さくすべく、各シャッタ片１９を矢印Ｒ方向に回動して閉動作するとき、各シャッタ片１９の先端部３５は、隣接したシャッタ片１９における押圧側面３１を摺動自在に押圧接触した状態にある。したがって、各シャッタ片１９における先端部３５と隣接したシャッタ片１９における押圧側面３１との間の間隙（クリアランス）は殆ど零に保持されるものである。 As shown in FIG. 4A, when each shutter piece 19 is rotated in the direction of the arrow R and closed to reduce the surrounding area 37 surrounded by the plurality of shutter pieces 19, The distal end portion 35 is in a state in which the pressing side surface 31 of the adjacent shutter piece 19 is slidably pressed and contacted. Therefore, the gap (clearance) between the front end portion 35 of each shutter piece 19 and the pressing side surface 31 of the adjacent shutter piece 19 is kept almost zero.
　上述のように、各シャッタ片１９における先端部３５が隣接したシャッタ片１９における押圧側面３１に常に押圧接触した状態にあると、先端部３５が摩耗し易いと共に、摩擦熱を生じてシャッタ片１９が熱膨張し、シャッタ装置１５における負荷が増大することがある。したがって、本実施形態においては、シャッタ片１９の閉動作時に、シャッタ片１９の先端部側が閉動作方向の逆方向へ撓むことを許容し得る構成としてある。 As described above, when the tip portion 35 of each shutter piece 19 is always in press contact with the pressing side surface 31 of the adjacent shutter piece 19, the tip portion 35 is easily worn and frictional heat is generated to cause the shutter piece 19. May thermally expand, and the load on the shutter device 15 may increase. Therefore, in the present embodiment, when the shutter piece 19 is closed, the distal end side of the shutter piece 19 is allowed to bend in the direction opposite to the closing operation direction.
　より詳細には、シャッタ片１９を構成する前記各半シャッタ片２９において前記ベース部材２７と前記先端部３５との間に、先端部側が閉動作方向の反対側方向へ撓むことを許容する撓み許容部３９が備えられている。上記撓み許容部３９として、本実施形態においては、各半シャッタ片２９における非押圧面３３側から押圧面３１方向へ形成したスリット４１にて例示してある。このスリット４１の先端位置４１Ａは、半シャッタ片２９における先端側部分４３が撓むときの支点となるものである。 More specifically, in each of the semi-shutter pieces 29 constituting the shutter piece 19, the deflection that allows the distal end side to bend in the direction opposite to the closing operation direction between the base member 27 and the distal end portion 35. An allowance unit 39 is provided. In the present embodiment, the bending allowance portion 39 is exemplified by a slit 41 formed in the direction of the pressing surface 31 from the non-pressing surface 33 side in each half-shutter piece 29. The tip position 41A of the slit 41 serves as a fulcrum when the tip side portion 43 of the half shutter piece 29 is bent.
　上記先端位置４１Ａの形状及び位置は任意の形状、任意の位置とすることができる。しかし、先端側部分４３の撓みを生じ易くするには、前記取付孔２５の中心位置Ｏと前記先端部３５とを結ぶ直線位置付近、又は上記直線位置と前記押圧側面３１との間の所望位置とすることが望ましいものである。 The shape and position of the tip position 41A can be an arbitrary shape and an arbitrary position. However, in order to easily cause the distal end side portion 43 to bend, a desired position between the linear position connecting the center position O of the mounting hole 25 and the distal end portion 35, or between the linear position and the pressing side surface 31. Is desirable.
　上記構成により、前述したようにシャッタ片１９の閉動作を行うとき、シャッタ片１９の先端部３５が隣接したシャッタ片１９の押圧側面３１に強く押圧接触する場合には、前記スリット４１の間隔を小さくするように、先端側部分４３に撓みを生じることになる。したがって、隣接したシャッタ片１９の押圧側面３１に対する先端部３５の強固な押圧接触が解除されることとなり、シャッタ片１９における先端部３５は、隣接したシャッタ片１９における押圧側面３１に常に円滑に摺接することとなり、負荷が過大になることを抑制することができるものである。 With the above configuration, when the closing operation of the shutter piece 19 is performed as described above, when the distal end portion 35 of the shutter piece 19 strongly presses and contacts the pressing side surface 31 of the adjacent shutter piece 19, the interval between the slits 41 is set. The tip side portion 43 is bent so as to be small. Therefore, the firm pressing contact of the tip 35 with the pressing side 31 of the adjacent shutter piece 19 is released, and the tip 35 of the shutter piece 19 always slides smoothly on the pressing side 31 of the adjacent shutter piece 19. Therefore, it is possible to suppress an excessive load.
　すなわち、シャッタ片１９の押圧側面３１に対して、隣接したシャッタ片１９の先端部３５が摺動自在に接触する接触圧は、常に適正な接触圧に保持されることになるものである。 That is, the contact pressure at which the tip portion 35 of the adjacent shutter piece 19 slidably contacts the pressing side surface 31 of the shutter piece 19 is always maintained at an appropriate contact pressure.
　また、シャッタ片１９の先端部３５が隣接したシャッタ片１９における押圧側面３１に常に摺接して閉動作を行うことにより、摺動部分に摩擦熱が発生し、シャッタ片１９が熱膨張することがある。この場合、シャッタ片１９の熱膨張によって、シャッタ片１９における先端部３５は、隣接したシャッタ片１９における押圧側面３１をより強固に押圧することになる。しかし、前記スリット４１の存在により、前記押圧時の反力によって先端側部分４３に撓みを生じるものである。したがって、シャッタ片１９に熱膨張が生じた場合であっても、シャッタ片１９における先端部３５と隣接したシャッタ片３９における押圧側面３１との摺動は円滑に行われるものである。すなわち、接触圧は常に適正な接触圧に保持されるものである。 Further, when the distal end portion 35 of the shutter piece 19 is always in sliding contact with the pressing side surface 31 of the adjacent shutter piece 19 to perform the closing operation, frictional heat is generated in the sliding portion, and the shutter piece 19 is thermally expanded. is there. In this case, due to the thermal expansion of the shutter piece 19, the distal end portion 35 of the shutter piece 19 presses the pressing side surface 31 of the adjacent shutter piece 19 more firmly. However, due to the presence of the slit 41, the tip side portion 43 is bent by the reaction force during the pressing. Therefore, even when thermal expansion occurs in the shutter piece 19, sliding between the front end portion 35 of the shutter piece 19 and the pressing side surface 31 of the adjacent shutter piece 39 is performed smoothly. That is, the contact pressure is always maintained at an appropriate contact pressure.
　なお、本発明は、前述したごとき実施形態のみに限ることなく、適宜の変更を行うことにより、その他の形態で実施可能なものである。すなわち、本発明の第２の実施形態では、撓み許容部３９の構成として、前記スリット４１に代えて、図５，６に示すように、非押圧側面３３側に適宜形状、大きさの切欠部４５を形成した構成とすることも可能である。すなわち、前記撓み許容部３９は、シャッタ片１９における先端部３５と隣接したシャッタ片１９における押圧側面３１との接触圧が過大になることを抑制し得れば良いものである。したがって、スリット４１に代えて丸穴や長穴とすることも可能である。また、スリット４１の形状としては直線的なスリット、湾曲したスリット、波形のスリット、Ｌ形状のスリットなど種々の形状とすることができるものである。 It should be noted that the present invention is not limited to the embodiment described above, and can be implemented in other forms by making appropriate changes. That is, in the second embodiment of the present invention, as a configuration of the bending allowance portion 39, instead of the slit 41, as shown in FIGS. A configuration in which 45 is formed is also possible. That is, the bending allowance portion 39 only needs to be able to suppress an excessive contact pressure between the front end portion 35 of the shutter piece 19 and the pressing side surface 31 of the adjacent shutter piece 19. Accordingly, a round hole or a long hole can be used instead of the slit 41. The slit 41 can have various shapes such as a linear slit, a curved slit, a corrugated slit, and an L-shaped slit.
　図７はシャッタ片の第３の実施形態を示すものである。この第３の実施形態に係るシャッタ片１９Ａは、前記特許文献１の図１３、特許文献２の図８に示されたごときシャッタ片にスリット４１を備えた構成を示すものである。この構成においても、前述した構成と同様の効果を奏し得るものである。 FIG. 7 shows a third embodiment of the shutter piece. The shutter piece 19A according to the third embodiment shows a configuration in which a slit 41 is provided in the shutter piece as shown in FIG. 13 of Patent Document 1 and FIG. 8 of Patent Document 2. Also in this configuration, the same effect as the above-described configuration can be obtained.
　図８，９は、本発明の第４の実施形態に係るシャッタ片１９Ｂを示すものである。このシャッタ片１９Ｂは、前記シャッタ片１９における前記取付ベース２７に相当する取付ベース２７Ａを備えている。そして、この取付ベース２７Ａには、複数の取付ねじ４７を介して前記半シャッタ片２９に相当する半シャッタ片２９Ａが取付けてある。この半シャッタ片２９Ａには、前記押圧側面３１及び非押圧側面３３に相当する押圧側面３１Ａ及び非押圧側面３３Ａが備えられている。さらに、半シャッタ片２９Ａには、前記先端部３５に相当する先端部３５Ａが備えられている。 8 and 9 show a shutter piece 19B according to the fourth embodiment of the present invention. The shutter piece 19B includes an attachment base 27A corresponding to the attachment base 27 in the shutter piece 19. A half shutter piece 29 </ b> A corresponding to the half shutter piece 29 is attached to the attachment base 27 </ b> A via a plurality of attachment screws 47. This half shutter piece 29A is provided with a pressing side surface 31A and a non-pressing side surface 33A corresponding to the pressing side surface 31 and the non-pressing side surface 33. Further, the half shutter piece 29A is provided with a tip portion 35A corresponding to the tip portion 35.
　前記取付ベース２７Ａに対して、前記半シャッタ片２９Ａは、互に接近離反する方向へ個別に調節可能に取付けてある。すなわち、前記取付ベース２７Ａの複数個所には偏心調節機構４９が備えられている。上記偏心調節機構４９は、図１０に示すとおりである。すなわち、前記取付ベース２７Ａの下面には円形状の凹部５１が形成してあり、この凹部５１の中心位置にはねじ穴５３が連通してある。そして、上記ねじ穴５３の周囲には複数の係止孔５５が穿設してある（図８、図９参照）。 The half-shutter piece 29A is attached to the attachment base 27A so as to be individually adjustable in a direction approaching and separating from each other. That is, an eccentricity adjusting mechanism 49 is provided at a plurality of locations on the mounting base 27A. The eccentricity adjusting mechanism 49 is as shown in FIG. That is, a circular recess 51 is formed on the lower surface of the mounting base 27 </ b> A, and a screw hole 53 is communicated with the central position of the recess 51. A plurality of locking holes 55 are formed around the screw hole 53 (see FIGS. 8 and 9).
　前記半シャッタ片２９Ａには、前記凹部５１に嵌合自在な軸部５７Ａを有する偏心部材５７が回動自在に備えられている。この偏心部材５７には、偏心カム部５７Ｂが一体的に設けられていて、当該偏心カム部５７Ｂには、前記係止孔５５に対して係脱自在な係止ピン５９が備えられている。そして、前記半シャッタ片２９Ａ、偏心部材５７を貫通して先端部を前記ねじ穴５３に螺合自在な前記取付ねじ４７が備えられている。 The half shutter piece 29A is rotatably provided with an eccentric member 57 having a shaft portion 57A that can be fitted into the recess 51. The eccentric member 57 is integrally provided with an eccentric cam portion 57 </ b> B, and the eccentric cam portion 57 </ b> B is provided with a locking pin 59 that can be engaged and disengaged with respect to the locking hole 55. The mounting screw 47 is provided through the half-shutter piece 29A and the eccentric member 57 so that the tip can be screwed into the screw hole 53.
　上記構成により、半シャッタ片２９Ａに対して偏心部材５７を適宜に回動し、当該偏心部材５７の軸部５７Ａを取付ベース２７Ａの凹部５１に嵌合すると共に、偏心部材５７の偏心カム部５７Ｂに備えた係止ピン５９を適宜位置の係止孔５５に係止することにより、取付ベース２７Ａに対して半シャッタ片２９Ａは、図１０において左右方向に僅かに位置調節されるものである。そして、取付ねじ４７をねじ穴５３に螺入して締付けることにより、取付ベース２７Ａと半シャッタ片２９Ａは一体的に固定されるものである。 With the above configuration, the eccentric member 57 is appropriately rotated with respect to the half-shutter piece 29A, the shaft portion 57A of the eccentric member 57 is fitted into the concave portion 51 of the mounting base 27A, and the eccentric cam portion 57B of the eccentric member 57 is provided. The half shutter piece 29A is slightly adjusted in the left-right direction in FIG. 10 with respect to the mounting base 27A. Then, the mounting base 27A and the half shutter piece 29A are integrally fixed by screwing the mounting screw 47 into the screw hole 53 and tightening.
　上記説明より理解されるように、シャッタ片１９Ｂにおける取付ベース２７Ａに対して各半シャッタ片２９Ａは個別に位置調節可能なものである。換言すれば、各半シャッタ片２９Ａの先端部３５Ａが摩耗した場合に、その摩耗量に対応して、取付ベース２７Ａに対して各半シャッタ片２９Ａの取付状態が調節可能なものである。したがって、シャッタ片２９Ａにおける先端部３５Ａと隣接したシャッタ片２９Ａにおける押圧側面３１Ａとの押圧接触状態を、常に適正な接触状態に調節可能なものである。この際、取付ベース２７Ａに対して各半シャッタ片２９Ａは個別に調節可能であるから、各半シャッタ片２９Ａに、仮りに製造誤差や熱膨張の差があるような場合であっても容易に対応し得るものである。 As can be understood from the above description, the position of each half-shutter piece 29A can be individually adjusted with respect to the mounting base 27A of the shutter piece 19B. In other words, when the tip portion 35A of each half-shutter piece 29A is worn, the attachment state of each half-shutter piece 29A can be adjusted with respect to the attachment base 27A in accordance with the wear amount. Therefore, the pressing contact state between the front end portion 35A of the shutter piece 29A and the pressing side surface 31A of the adjacent shutter piece 29A can be always adjusted to an appropriate contact state. At this time, since each half-shutter piece 29A can be individually adjusted with respect to the mounting base 27A, even if each half-shutter piece 29A has a manufacturing error or a difference in thermal expansion, it is easy. It can respond.
　前記シャッタ片１９Ｂにおける各半シャッタ片２９Ａには、撓み許容部としてスリット４１Ｂが形成してある。このスリット４１Ｂには、シャッタ片１９Ｂにおける先端側部分４３Ａの撓み量を調節するための撓み量調節機構６１が備えられている。より詳細には、前記スリット４１Ｂには、複数のピン挿入部６３Ａ，６３Ｂ，６３Ｃが適宜間隔に備えられている。そして、適宜位置のピン挿入部６３Ａ，６３Ｂ，６３Ｃには、スリット間隔規制部材の１例としての調節ピン６５が挿入離脱自在に挿入してある。 A slit 41B is formed in each half-shutter piece 29A in the shutter piece 19B as a bending allowance portion. The slit 41B is provided with a bending amount adjusting mechanism 61 for adjusting the bending amount of the distal end side portion 43A of the shutter piece 19B. More specifically, the slit 41B is provided with a plurality of pin insertion portions 63A, 63B, 63C at appropriate intervals. An adjustment pin 65 as an example of a slit interval regulating member is inserted into the pin insertion portions 63A, 63B, 63C at appropriate positions so as to be freely inserted and removed.
　したがって、先端側部分４３Ａに撓みを生じて、スリット４１Ｂの間隔を狭めようとすると、スリット４１Ｂ内に調節ピン６５を挟み込むこととなり、先端側部分４３Ａの撓み量が制限されるものである。なお、先端側部分４３Ａの撓み量を調節する際は、ピン挿入部６３Ａ，６３Ｂ，６３Ｃを選択することによって調節することができる。又径の異なる複数の調節ピン６５を備え、所望径の調節ピン６５を選択して所望のピン挿入部６３Ａ，６３Ｂ，６３Ｃに挿入することによっても、調節ピン６５の外周面とピン挿入部６３Ａ，６３Ｂ，６３Ｃの内周面とのクリアランスを調節でき、先端側部分４３Ａの撓み量を調節することができるものである。さらには、弾性係数の異なる複数の調節ピン６５を備え、所望の弾性係数の調節ピン６５を選択することによっても、前記先端側部分４３Ａの撓み量を調節することができるものである。 Therefore, if the tip side portion 43A is bent and the interval between the slits 41B is narrowed, the adjustment pin 65 is sandwiched in the slit 41B, and the amount of deflection of the tip side portion 43A is limited. In addition, when adjusting the amount of bending of the distal end side portion 43A, it can be adjusted by selecting the pin insertion portions 63A, 63B, 63C. Also, a plurality of adjustment pins 65 having different diameters are provided, and the outer peripheral surface of the adjustment pin 65 and the pin insertion portion 63A can be selected by selecting the adjustment pin 65 having a desired diameter and inserting it into the desired pin insertion portions 63A, 63B, 63C. , 63B, 63C can be adjusted with respect to the inner peripheral surface, and the amount of deflection of the distal end side portion 43A can be adjusted. Furthermore, the amount of deflection of the distal end portion 43A can be adjusted by providing a plurality of adjustment pins 65 having different elastic coefficients and selecting the adjustment pins 65 having a desired elastic coefficient.
　なお、径の異なる複数の調節ピン６５を備える場合、又は弾性係数の異なる複数の調節ピン６５を備える場合には、前記ピン挿入部６３Ａ，６３Ｂ，６３Ｃは、所望位置の１つとすることも可能である。 When a plurality of adjustment pins 65 with different diameters are provided, or when a plurality of adjustment pins 65 with different elastic coefficients are provided, the pin insertion portions 63A, 63B, 63C can be one of desired positions. It is.
　さらに、撓み量調節機構６１の構成としては、図１１に示すごとき構成とすることも可能である。すなわち、スリット４１Ｂ内の適宜位置に、傾斜面６７Ｓが対向したスリット間隔規制部材の１例としての傾斜部材６７をスリット４１Ｂの間隔方向に対向して備える。そして、少なくとも一方の傾斜部材６７をスリット４１Ｂの長手方向（矢印方向）へ位置調節可能な構成とする。この構成によれば、傾斜部材６７における傾斜面６７Ｓの間隔を所望の間隔に調節することができるものである。したがって、半シャッタ片２９Ａにおける先端側部分４３Ａの撓み量を制限することができ、撓み量を調節することができるものである。 Furthermore, the configuration of the deflection amount adjusting mechanism 61 may be as shown in FIG. That is, an inclined member 67 as an example of a slit interval regulating member with the inclined surface 67S facing is provided at an appropriate position in the slit 41B so as to be opposed to the interval direction of the slit 41B. The position of at least one of the inclined members 67 can be adjusted in the longitudinal direction (arrow direction) of the slit 41B. According to this configuration, the interval between the inclined surfaces 67S of the inclined member 67 can be adjusted to a desired interval. Therefore, the amount of deflection of the tip side portion 43A of the half shutter piece 29A can be limited, and the amount of deflection can be adjusted.
　また、撓み量調節機構６１の構成としては、スリット４１Ｂに並列して、適宜クリアランス、適宜長さの別個のスリットを備える構成とすることも可能である。 Further, as the configuration of the bending amount adjusting mechanism 61, it is possible to have a configuration in which a separate slit having an appropriate clearance and an appropriate length is provided in parallel with the slit 41B.
　すなわち、撓み量調節機構６１としてはスリット４１Ｂの間隔寸法（幅寸法）が必要以上に小さくなることを制限し得る構成であればよく、例えばスリット４１Ｂ内に適宜厚さのスペーサ又はブロックを配置する構成など種々の構成を採用することができるものである。 In other words, the bending amount adjusting mechanism 61 may be configured to be able to restrict the interval dimension (width dimension) of the slit 41B from becoming unnecessarily small. For example, a spacer or a block having an appropriate thickness is disposed in the slit 41B. Various configurations such as a configuration can be employed.
　上記構成により、シャッタ片１９Ｂにおける先端部３５Ａが隣接したシャッタ片１９Ｂにおける押圧側面３１Ａを押圧して摺動する際の接触圧が過大になることを抑制することができるものである。したがって、シャッタ片１９Ｂが熱膨張した場合であっても、前記接触圧を適正の接触圧に調節することが可能なものである。 With the above configuration, it is possible to suppress an excessive contact pressure when the tip 35A of the shutter piece 19B slides by pressing the pressing side surface 31A of the adjacent shutter piece 19B. Therefore, even when the shutter piece 19B is thermally expanded, the contact pressure can be adjusted to an appropriate contact pressure.
　前述したように、シャッタ片１９Ｂの先端部３５Ａが隣接したシャッタ片１９Ｂの押圧側面３１に押圧接触して摺動することにより摩擦熱が発生した場合に、シャッタ片１９Ｂの放熱を行うための放熱部６９が備えられている。より詳細には、図８に示すように、前記シャッタ片１９Ｂにおける各半シャッタ片２９Ａの先端側部分４３Ａには、上下に貫通した貫通孔７１が形成してある。そして、この貫通孔７１内には、熱伝導のよい金属製のパイプ材７３が嵌入（挿入）してある。 As described above, when the frictional heat is generated when the tip 35A of the shutter piece 19B slides in contact with the pressing side surface 31 of the adjacent shutter piece 19B, heat dissipation for radiating the shutter piece 19B is performed. A portion 69 is provided. More specifically, as shown in FIG. 8, a through-hole 71 penetrating vertically is formed in the tip end portion 43A of each half-shutter piece 29A in the shutter piece 19B. And in this through-hole 71, the metal pipe material 73 with good heat conduction is inserted (inserted).
　上記構成により、半シャッタ片２９Ａの先端部３５Ａと隣接した半シャッタ片２９Ａにおける押圧側面３１Ａとの摺動摩擦によって発生した熱は、半シャッタ片２９Ａに蓄熱される傾向にある。しかし、半シャッタ片２９Ａの熱が前記放熱部６９に伝達されると、当該放熱部６９において放熱が行われる。よって、半シャッタ片２９Ａに蓄熱されて半シャッタ片２９Ａが高温になることを抑制することができるものである。 With the above configuration, the heat generated by the sliding friction between the tip side 35A of the half shutter piece 29A and the pressing side surface 31A of the adjacent half shutter piece 29A tends to be stored in the half shutter piece 29A. However, when the heat of the half shutter piece 29 </ b> A is transmitted to the heat radiating unit 69, the heat radiating unit 69 radiates heat. Therefore, it is possible to prevent the heat from being stored in the half shutter piece 29A and the half shutter piece 29A from becoming high temperature.
　前記放熱部６９は、本実施形態においては、半シャッタ片２９Ａを上下に貫通した貫通孔７１内に金属製のパイプ材７３を嵌合した構成であるから、パイプ材７３内においては空気の上昇流が生じることとなり、半シャッタ片２９Ａの放熱冷却が行われるものである。 In the present embodiment, the heat dissipating part 69 has a configuration in which a metal pipe material 73 is fitted in a through hole 71 that vertically penetrates the half shutter piece 29A. As a result, a heat release cooling of the half-shutter piece 29A is performed.
　なお、前記放熱部６９の構成としては、半シャッタ片２９Ａの表面積をより大きくするために、貫通孔に代えて、上下両面に開口した穴又は溝或はそれらの組合せ等に構成することも可能である。この際、半シャッタ片２９Ａの回転時に、半シャッタ片２９Ａの表面に対して相対的に流れる空気との接触面積をより大きくするために、表面に襞を形成することも可能である。 The heat dissipating part 69 may be configured with holes or grooves opened on both upper and lower surfaces, or a combination thereof, in place of the through holes, in order to increase the surface area of the half shutter piece 29A. It is. At this time, in order to increase the contact area with the air flowing relative to the surface of the half-shutter piece 29A when the half-shutter piece 29A rotates, it is possible to form a ridge on the surface.
　既に理解されるように、シャッタ片１９Ｂにおける半シャッタ片２９Ａに放熱部６９を備えているので、シャッタ片１９Ｂの温度上昇を抑制することができ、熱膨張を抑制することができるものである。 As already understood, since the heat radiation part 69 is provided in the half-shutter piece 29A in the shutter piece 19B, the temperature rise of the shutter piece 19B can be suppressed, and the thermal expansion can be suppressed.
　前記構成のごときシャッタ片を、前記食品成形装置１におけるシャッタ装置１５の回転軸１７に取付けて、食品生地の包被切断を行う場合、各シャッタ片に備えた撓み許容部の作用によって、各シャッタ片の先端側部分を、各シャッタ片が閉動作を行う閉動作方向の逆方向へ撓むことを許容して閉動作を行うものである。したがって、シャッタ片における先端部が隣接したシャッタ片における押圧側面に接触する接触圧を常に適正の接触圧に保持して包被切断を行うことができるものである。 When the shutter piece having the above-described configuration is attached to the rotating shaft 17 of the shutter device 15 in the food molding apparatus 1 and the food dough is encased and cut, each shutter piece is acted upon by the action of the deflection allowing portion provided in each shutter piece. The tip end side portion of the piece is closed by allowing the shutter pieces to bend in the direction opposite to the closing operation direction in which each shutter piece performs the closing operation. Therefore, it is possible to cut the envelope while always maintaining the contact pressure at which the tip of the shutter piece contacts the pressing side surface of the adjacent shutter piece at an appropriate contact pressure.
　したがって、シャッタ片における先端部と隣接したシャッタ片の押圧側面との摩擦による摩擦熱の発生を抑制できることとなり、シャッタ片の熱膨張に起因する負荷の増大を抑制できるものである。 Therefore, generation of frictional heat due to friction between the front end portion of the shutter piece and the pressing side surface of the adjacent shutter piece can be suppressed, and an increase in load due to thermal expansion of the shutter piece can be suppressed.
　なお、前記説明においては、シャッタ片を一方向へ回転して食品生地の包被切断を行う場合について説明した。しかし、シャッタ片を往復回動（揺動）することによって包被切断を行うことも可能である。さらには、前記特許文献４に記載されているように、シート状の外皮材の周縁部を中央部に寄せ集めるためのシャッタ装置におけるシャッタ片にも適用可能なものである。 In the above description, the case where the food dough is covered and cut by rotating the shutter piece in one direction has been described. However, it is also possible to cut the envelope by reciprocatingly rotating (swinging) the shutter piece. Furthermore, as described in Patent Document 4, the present invention can also be applied to a shutter piece in a shutter device for gathering the peripheral edge of a sheet-like outer skin material at the center.
以上、本願発明を上述した実施例に基づき具体的に説明したが、本発明は、上述した発明の実施例に限定されるものではなく、その要旨を逸脱しない範囲において種々変更可能である。 The present invention has been specifically described above based on the above-described embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.
　なお、日本国特許出願第２０１４－２１２３４６号（２０１４年１０月１７日出願）及び日本国特許出願第２０１４－０１４７３５号（２０１４年１月２９日出願）の全内容が、参照により、本願明細書に組み込まれている。 The entire contents of Japanese Patent Application No. 2014-212346 (filed on October 17, 2014) and Japanese Patent Application No. 2014-014735 (filed on January 29, 2014) are incorporated herein by reference.
